M4 Double Slot Mushroom Head Screws NF E 25-129 in A2 Stainless Steel

Double slotted mushroom head machine screws manufactured to NF E 27-128 feature a wide, low-profile head that provides an increased bearing surface compared with conventional pan head screws. This makes them particularly suitable for fastening softer materials or applications where the clamping load needs to be distributed over a larger area to help reduce the risk of surface damage.
